[PATCH v3 1/5] target: ensure se_cmd->t_prot_sg is allocated when required

Even if the device backend is initialized with protection info is enabled, some requests don't have the protection info attached for WRITE SAME command issued by block device helpers, WRITE command with WRPROTECT=0 by SG_IO ioctl, etc. So when TCM loopback fabric module is used, se_cmd->t_prot_sg

[PATCH v3 5/5] target/file: enable WRITE SAME when protection info is enabled

Now we can generate correct PI for WRITE SAME command, so it is unnecessary to disallow WRITE SAME when protection info is enabled. Signed-off-by: Akinobu Mita Cc: Nicholas Bellinger Cc: Sagi Grimberg Cc: "Martin K. Petersen" Cc: Christoph Hellwig Cc: "James E.J. Bottomley" Cc: target-de...@

[PATCH v3 4/5] target: Fix sbc_dif_generate() and sbc_dif_verify() for WRITE SAME

For WRITE SAME, data transfer memory only contains a single block but protection information is required for all blocks that are written by the command. This makes sbc_dif_generate() and sbc_dif_verify() work for WRITE_SAME. Signed-off-by: Akinobu Mita Cc: Nicholas Bellinger Cc: Sagi Grimberg

[PATCH v3 3/5] target: handle odd SG mapping for data transfer memory

sbc_dif_generate() and sbc_dif_verify() currently assume that each SG element for data transfer memory doesn't straddle the block size boundary. However, when using SG_IO ioctl, we can choose the data transfer memory which doesn't satisfy that alignment requirement. In order to handle such cases

[PATCH] scatterlist: enable sg chaining for all architectures

Some architectures enable sg chaining option while others do not. The requirement to enable sg chaining is that pages must be aligned at a 32-bit boundary in order to overload the LSB of the pointer. Regardless of whether ARCH_HAS_SG_CHAIN is defined or not, the above requirement is always chacked
